In my case it's much more practical to ie use pattern in ssh config for
all the test envs instead of listing plenty of them explicitly.

It's nice to have a possibility to customize behavior but I'd say more
sensible default would be to offer both. Or in other words current
default behavior is somewhat counter-intuitive. Doing "build<tab>"
offers single completion, while doing more specific "builder<tab>"
offers 3. Intuitively with every char completion options should be
narrowed (or remain the same) but should not be broadened.
